Callers must pass ELF machine, byte swapping and symbol LSB clearing
information to ELF loader. A.out loader needs page size information, pass
that too as a parameter.
Extract prototypes to a separate file. Move loader.[ch] and elf_ops.h under hw.
Adjust callers. Also use target_phys_addr_t instead of target_ulong for
addresses: loader addresses aren't virtual.

With this patch applied ide drives (when attached to a pci adapter) can
be created via -device, like this:
-drive if=none,id=mydisk,file=/path/to/disk.img
-device ide-drive,drive=mydisk,bus=ide.0,unit=0
Note that creating a master on ide1 doesn't work that way. That is a
side effect of qemu creating a cdrom automagically even if you don't
ask for it.

Build uset targers as true PIE if user want to keep qemu
self-virtualizable.
v5:
- Split into to patches: drop link hack and add PIE support
- do not build PIE by default and drop toolchain check
v4:
- Add test for toolchain if it has proper PIE support
v3:
- One more pice of the hack was removed
- Description updated
v2:
- Add configure options do enable/disable PIE for usermode targets.
Disabling can be useful if you build uswing toolchain which has
broken PIE support. PIE for usermode targets enabled by default.

-watchdog NAME is now equivalent to -device NAME, except it treats
option argument '?' specially, and supports only one watchdog.
A side effect is that a device created with -watchdog may now receive
a different PCI address.
i6300esb is now available on any machine with a PCI bus, not just PCs.
ib700 is still PC only, but that could be changed easily.
The only remaining use of struct WatchdogTimerModel and
watchdog_add_model() is supporting '-watchdog ?'. Should be replaced
by searching device_info_list for watchdog devices when we can
identify them there.
Also fixes ib700 not to use vm_clock before it is initialized: in
wdt_ib700_init(), called from register_watchdogs(), which runs before
init_timers(). The bug made ib700_write_enable_reg() crash in
qemu_del_timer().

Introduce isa_reserve_irq() which marks an irq reserved and returns
the appropriate qemu_irq entry from the i8259 table.
isa_reserve_irq() is a temporary interface to be used to allocate ISA
IRQs for devices which have not yet been converted to qdev, and for
special cases which are not suited for qdev conversions, such as the
'ferr'.
This patch goes on top of Gerd Hoffmann's which makes isa-bus.c own
the ISA irq table.

kqemu introduces a number of restrictions on the i386 target. The worst is that
it prevents large memory from working in the default build.
Furthermore, kqemu is fundamentally flawed in a number of ways. It relies on
the TSC as a time source which will not be reliable on a multiple processor
system in userspace. Since most modern processors are multicore, this severely
limits the utility of kqemu.
kvm is a viable alternative for people looking to accelerate qemu and has the
benefit of being supported by the upstream Linux kernel. If someone can
implement work arounds to remove the restrictions introduced by kqemu, I'm
happy to avoid and/or revert this patch.
N.B. kqemu will still function in the 0.11 series but this patch removes it from
the 0.12 series.
Paul, please Ack or Nack this patch.

Currently Qemu can read from posix I/O and NBD. This patch adds a
third protocol to the game: HTTP.
In certain situations it can be useful to access HTTP data directly,
for example if you want to try out an http provided OS image, but
don't know if you want to download it yet.
Using this patch you can now try it on on the fly. Just use it like:
qemu -cdrom http://host/path/my.iso

This patch adds a network interface backend driver to qemu. It is a pure
userspace implemention using the gntdev interface. It uses "qnet" as
backend name in xenstore so it doesn't interfere with the netback
backend (aka "vnif").
The network backend is hooked into the corrosponding qemu vlan, i.e.
vif 0 is hooked into vlan 0. To make the packages actually arrive
somewhere you additionally have to link the vlan to the outside world
using the usual qemu command line options such as "-net tap,...".
